Here one very interesting antenna - La Fontenna Clone.
It was interesting what is inside FON antenna. On site specs they give it 7dbi or 6.5dbi with 3m low loss coax.
On one Italian blog I found dimensions for building a clone of La Fontenna.
Saved long long ago from an old Russian forum: wifi-connect.ru
The site is running now again, but without a forum, and no new info is available.
This is just a bigger version of previous coax antenna.

There is no info available about gain or anything els.
Used coax is RG-213
On site also suggest some sort of franklin dipole :
I thing that this design will be fun to test.
May be will work ? What you thing ?

I cant find original site of this antenna there is links on Zero13wireless forum.
I cut a lot of coax without any success before time in attempt to make a coax omni antenna.
This thing here is looking different. But maybe will work.
This is the idea :
30mm in the beginig 1/4 wave - may be patching section.
40 mm of outer of coax is used to dephaseing sections.
60 mm sections as 1/2 wave radiators.
And that is.
